钛合金和碳纤维材料因其优良的性能，在飞机的结构材料中被大量使用。针对飞机红外偏振探测的需求，以钛合金板、碳纤维板以及喷涂红外伪装涂料的上述两种目标板为实验样品，开展了红外偏振光谱探测实验，结果表明，在 8～14 .m热红外波段 4种材料样本的偏振度随观测角度的增大而增大、随波长的变化无明显规律，普通红外伪装涂料无法提供偏振伪装。

Titanic alloy and carbon fiber are widely used in aircraft because of their excellent characteristics. Taking the titanic alloy plate, carbon fiber plate and the same plates coated with camouflage coating respectively as the target plates, the infrared polarization experiments were conducted in order to detect the aircraft by using infrared polarization technology. The experiment results show that the polarization degree of plates increases with the viewing angle, but without obvious changes with the wavelength in 8~14.m infrared wave band. Infrared camouflage coatings cannot provide the stealthy ability in infrared polarization detection technology.研究资助项目
